Originally delivered as a lecture at the LSE this article finds Strange explicitly engaging with the notion of globalisation. For Strange globalisation is: the development of products for explicitly global and transnational markets; the decline of barriers and distinctions between national economies; the emergence of at least partial labour mobility in addition to the more recognised capital mobility; and the speeding up of transport and communications. While these trends have changed the balance between authority and markets over outcomes in the international political economy, they have also led to an increasingly globalised but asymmetrical array of structural power.
